 #### Specify custom boundaries for Histogram
 
 By default, the boundaries used for a Histogram are [`{ 0, 5, 10, 25, 50, 75,
-100, 250, 500,
-1000}`](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/sdk.md#explicit-bucket-histogram-aggregation).
